# Scrawler I vs Knowledge Robo

The clearest difference is rating: Scrawler I at 3.9 against Knowledge Robo's 3.0. Scrawler I also leads on in-app purchases (none vs 2) and ratings volume (10 vs 2). Knowledge Robo's advantage is review sentiment (100% vs 74%). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Knowledge Robo sells 2 one-off in-app purchases. Scrawler I asks for nothing beyond the download.

Scrawler I holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Scrawler I has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 74% of Scrawler I's written reviews are positive against 100% of Knowledge Robo's, so the app with the better star average is not the one people write more warmly about.
